Application filed October 14, 1ei4. Serial No. saacw.

To all whom-it may concern Be it known that I, BENJAMIN C. LoRrNe,residing at of Wayne. and State of Michigan, have invented-certain newand useful Improvements in Wind-Shield Cleaners, of which -the followingis a specification.

This invention relates to means for wiping or scraping a portion of amotor vehicle wind-shield to restore the transparency of the shield byremoving moisture and dirt from the front side therebeing operable bytheoccupying his usual seat.

The invention is embodied in a cleaning device, including an elongatedscraper, an

oscillatory arm maintaining the scraper 1n yielding contact with thefront side of a across a predetermined part of the shield, thev scraperbeing separable from the arm when -Fig. 4 represents a section windshield and adapted to move the scraper swung to a predetermined positionrelatively to the arm, and means loosely connecting the inner end of thescraper with a fixed support on a wind shield to cause the scraper to.swing with the arm and prevent the scraper from swinging to positionfor separation from the arm, said means being separable from the scraperto permit separation of the latter from the, arm.

The invention consists in the improvements which I will now proceed todescribe and claim.

Of the accompanying drawings, forming a part of. this specification,Figure 1 represents an elevation of a portion of the front side of awind shield equipped with a cleaner embodying my sents a section on line2 -2 represents a section on line of Fig. 1. Fig. 3 3-3 of Fig. 1. online 4' 4 of Fig. 1. Fig. 5 represents asection on line 5-5 of Fig. 2.Fig. 6 represents an elevation on front side of a wind shield and acleaner mounted thereon, the cleaner being atone extreme ofits-oscillating movement.

The same letters of reference indicate, the same parts in all ofthefigures.

In thedrawings, 05 represents the frame and b the glass of the windshield, which may-be of any suitable construction.

The cleaner of my invention includes a bearing adapted to support arock-shaft '12 extending crosswise of the front side turned to cause the,rod, bent as shown,

invention. Fig. 2 reprea reduced scale of a portion of theof the windshield.

GLORING, 'rnus'rnns, on imi Said bearing, inthe preferred embodiment ofthe invention here shown, is formed by the walls of orifices 13, (Fig.3), formed in two jaws 14, 14, which are adapted to bear on oppositesides of the frame a, and are.

adjustably connected byscrews 15, the inner jaw 14 having a rib orflange 16, seated in a. groove 17 in the outer jaw 14"", as shown byFig. 4. Said flange covers the space between the upper ends of the jawsand prevents said upper ends from moving toward each other whenthescrews 15 are lower portions of the jaws to grip the frame a.

The rock-shaft 12 is provided at one end with an operating crank orhandle 19, whereby it may be rocked in its bearing, said handle being atthe inner side of the shield, and at the other end with a resilient arm20, which projects over the outer side of theshield and is normallyunder tension,

tending to press its outer end inwardly toward the shield, as indicatedby dotted lines in Fig. 2. v The rock-shaft 12, handle 19,

and arm 20, are preferably made from a single resilient substantiallyU-shaped metal the handle and arm proj ecting in the same shaft, andconstituting stops cooperating with the bearing in preventing endwisedis: placement of the rock shaft which is formed by the neck portion ofthe U-shaped rod.

The acting or gated scraper which is composed of a tubular sheet metal.back .22, having a longitudinal slot in one side and a blade 23- offlexible material, preferably rubber, in serted in said slot, asshown-by Fig. 5, the .outer edge of the blade projecting from [the backand bearing against the outer side of the shield b. There is a separablehinge connection between 20, ,said connection permitting the scraper toswing in various directions relative to the arm, the acting edge of thescraper blade being thus permitted 'to bear along its entire lengthlelism with the arm 20, as indicated by Fig. 6, when the scraper isatone extreme of its direction from'the rockcleamng member is an elonthescraper and the arm on the shield, and the scraper as a whole beingadapted to stand out of paralmovement, and lies parallel with a portionfull line i ever, that, since the hook 24 is of the arm 20 andconstituting one member of the connection, and a hole or eye 25 in thescraper back .22 at about its longitudinal center and constituting theother member of the connection,the said eye and hook being looselyinterengaged. ,The blade 23 is recessed at 23*" (Fig. 3) to permit thehook 24 to bear on the inner portion of the back 22. In assembling theparts the scraper is interposed between the arm 20 and the shield, andits hook is, inserted in the eye 25. This operation springs the arm. 20outwardly from the dotted line position to the position shown by Fig. 2,so that the arm positively exerts an inward pressure on the scraper,holding the edge of the blade 23 in close contact with the shield I)along its entire length.

It will now be seen that when the arm.

20 is oscillated by a rocking movement of the rock-shaft 12 in itsbearing, the scraper is moved with the arm. It is evident, how= adaptedto controlling the scraper turn in the eye 25, some form of means'lsrequlred to malntam in the operative position relatively to the arm 20,represented by Figs. 1 and 2, so that the scraper will be caused by theoscillations of the arm to move sidewise in a curved path, as indicatedby dotted lines in Fig. 6. The preferred form of controlling means isthat represented by the drawings, said means comprising a rigid car 27,formed on the jaw 14 and projecting below the same, and awire confimngrod 28 havin an eye 29 loosely engaged with the ear 2 and projectinginto the tubular back 22 of the scraper, the scraper being free tomovelengthwise, relatively to the rod. In other words, the scraper and rodare slidingly connected. en the parts are in the positionshown by Figs.1 and 2, the ear 27 and rod 28 maintain the scraper in apositionsubstantially parallel with the arm 20. en the parts are in the positionshown by Fig. 6, the scraper being at one extreme of its movement and inclose the scraper to stand out of parallelism with the arm20. When thescraper is in the position last described, it offers practically noobstruction to the view of the operator through the shiel When thedevice is operated, a movement of the scraper'from the position shown byFig. 6 to that shown by Fig. 1 gradually brings the scraper intoparallelism with the arm 20. The

ear'27 and rod 28 at all times control the position of the scraper andcause it to move sidewise in the predetermined path indicated, thescraper .in approaching either end of its movement assummg a positionout of parallelism with the arm 20, as indicated by Fig. 6.

The tension of the arm 20, the separable of the ing the scraper to swingits proximity to. the frame a, the ear 27 and rod 28 permit connected asshown with'che bearing hinge connection between said arm and thescraper, and the scraper-controlling means. are deslgned to maintain aumform pressure wardly by entire edge of the scraper blade .23

against the shield, regardless of wear of 7 0 the arm sufliciently tocompensate I for such wear until the-blade is entirely.

worn out.

' When the bearing is detached from the shield, the'scraper may beseparated from the arm 20 and confining rod 28 by first turning thebearing on the rock-shaft to withdraw the rod from the scraper back (therod being sufliciently loose in the back to permit this operation),

upper end to the rlght as viewed in Fig. 2. The latter opera tion causesthe wall of theorifice 25 to slide ofi from the hook 24. Provision istherefore made for quickly and conveniently removand then swing- Y ingthe scraper to permit the removal of a worn blade 25 and thesubstitution of a new blade therefor. The scraper is reengaged with thearm'20 and confining rod 28 by a reversal of the described operations,the scraper back being first engagedwith the hook 24, and the bearingbeing then turned on the rock-shaft to cause the rod to, enter the back,as shown by Fig. 1.

It will be seenthat when the rod'is inserted in the back, it preventsthe back from being swung in the direction required to separate the backfrom the arm 20, the back being removable from the hook 24 only by aswinging movement in a given direction, that is, in a direction whichmoves the upper end of the back to the right as viewed in ig. 2. Thismovement of the back is also prevented by the shield when the bearing isattached to the shield. No positive fastenings such as bolts, screws andnuts are used to separably connect the carrying arm and hearing, so thatthe scraper is applicable to and separable from the carrying arm andbearing without the use of tools and by a minimum expenditure of'time.

The bearing, the rock-shaft 12, the handle 19, the carrying arm 20, andthe scraper and the carrying arm, constitute a wind shield attachmentadapted to be installed on a Wind shield by the operation of attachingthe bearing to the shield, the scraper being maintained in separableengagement with the \Carrying arm and bearing as described, when thebearing is removed from the shield.

I do not limit myself to the described means for connecting therock-shaft bearing with the shield frame. said bearing may be a bushinginserted in an orifice formed for its reception within the frame,particularly when the latter is made of wood. i

It is obvious that K handle and. at the other end awiper-carryconnection between ing arm,

motion relatively to the arm,

The described construction enables a folding shield to be folded ineither direction, and enables a sliding shield to be moved ver tically,as usual, without obstruction by the cleaner to either of saidmovements.
